Effect of different cultural factors on the yield and agronomic traits of vegetable soybean.

Under the field experiment conditions,vegetable soybean variety Suxiandou No.20 was chosen to evaluate the effect of different cultural factors(fertilizer levels and planting densities)on yield and agronomic traits using randomized complete block design.The results showed as follows:the fresh yield of Suxiandou No.20 significantly different under different fertilizer levels,planting densities and their interaction.The highest yield in this experiment appeared in treatment with fertilizer level of PU50%+PCU50% and density of 3.0×105 plants·ha-1,its fresh pod yield could reach 9 045.11 kg·ha-1.Different fertilizer levels and planting densities had great influence on plant height and effective pods per plant,while branches,node number and 100-fresh grain weight were less influenced by different cultural factors.
